ABSTRACT

The present study was conducted during rabi, 2024-25 at the dryland Farm of S.V. Agricultural College, Tirupati, under Acharya N.G. Ranga Agricultural University, Andhra Pradesh. Twenty groundnut genotypes were evaluated to assess variability in morpho-physiological traits. The field experiment was laid out in Randomized Block Design (RBD) with three replications. Significant differences were observed among genotypes for all studied traits. Among the twenty genotypes, TAG-24 was the earliest maturing genotype, while Dheeraj exhibited the greatest plant height. TCGS-1694 and Kadiri-9 showed the highest leaf area index and SCMR, respectively. The findings indicate considerable genetic variability, offering scope for selection and improvement in groundnut breeding programs.
